Italians are white and make up a good chunk of the White American population and have contributed wonderfully to American society. Greeks are white too going back to the ancients. The USA is a continuation of White European society in the New World. A combination of the best of Anglo, Saxon, and Mediterranean European society. It was pretty awesome 'til recently.
Turkeys are native to the US, settlers just killed them and ate them here idk what that has to do with Aztecs they were thousands of miles away in modern day Mexico.
